Pretty good value from Aliexpress.
Of course the wind is deflected to the Helmet area but apart from that 8 can't complain at 50 bucks.

$50 is hard to argue with. If it keeps the wind off your chest without making helmet turbulence too bad, that's a pretty decent upgrade for the money.

Not fitted at present, I tried making my own screens and played with height, width and angles.
They seemed to just direct the wind to different areas and created noise.
So I gave up!,
I mostly only get to 100kph here and short runs are ok with no screen.
